BUCKLE.

SPECIFICATION forlfnng` part of Letters Patent No. 470,652, dated March15, 1892.

Application filed April 25,1891.

To all whom' it may concern:

Be it known that I, JOHN FRANCIS BAL- LARD, a subject of the Queen ofGreat Brit-ain, residing in the city of Hamilton, in the county 5 ofWentworth andProvince of Ontario, in the Dominion of Canada, haveinvented new and useful Improvements in Buckles, (for which I have notobtained a patent in any con ntry,) of which the following is aspecification.

My invention relates to buckles or fastenin gs for holdback-straps forbu ggies and other vehicles and for other purposes where from theunhitching or undoing of other fastenings, whether accidental orotherwise, it may I5 become desirable to have a buckle that willautomatically disengage itself .from its strap.

I attain this object by a buckle illustrated in the accompanyingdrawings, in Which- Figure l is a plan or top view of the buckle. 2oFig. 2 is a bottom view to show the manner in which the tongue isinserted. Fig. 3 is a section on line x of Fig. l. Fig. 4 is a sectiononline y y of Fig. l.

Similar letters refer to similar parts throughz 5 out the several views.p

The frame A of the buckle is of the usual kind. The fastener B, by Whichit is held to the shaft or other object, has a slot b on the under side,as shown in Fig. 3, to receive the Serial No. 390|482. (No model.)

frame A, and in which it is pivoted when the fastener B is lixed uponthe shaft. The fastener B has another slot b forward of the slot b',which slot b is intended to carry the pivots c c of the tongue C, sothat when the fastener B is fixed to the shaft the tongue O z5 will bepivoted therein.

It will be seen that the tongue C is not pivoted concentrically with theframe A, as is usual with buckles, but eccentrically. Consequently whenthe Whiffletrees or the traces are unhitched and a change in thedirection of the draft occurs, as shown by the dotted lines in Fig.3,the tongue O draws Wit-hin the frame A, so that the frame A becomesautomatically unhitched.

What I claim my as invention, and desire to secure by Letters Patent,is-

A buckle consisting of the frame A, fastener B, and tongue O, the frameA pivoted in a slot b in the fastener B, and the tongue O, by its pivotsc c, pivoted in another slot b in rsaid fastener B, all as hereinbeforedescribed, as and for the purposes hereinbofore set forth.
